Maximum Power - Precision Fitment - Incredible Sound

42 Draft Designs turbo-back exhaust system is the ultimate exhaust upgrade for your Mk1 Audi TT 225. Built right here in the USA, our unique turbo-back system delivers unbeatable power gains and exquisite sound without a single compromise.

This exhaust system is complete from turbo to tailpipe and includes everything necessary for successful installation. Two available options allow this system to be tailor-made to fit your vehicle.

To configure this system to meet your specific needs please browse the options above. More information about our exhaust systems is available by following the links below.

If your car is still equipped with OEM engine/transmission/dogbone mounts fitment issues may arise. As these vehicles age, OEM mounts tend to sag due to the weight of the engine and transmission hanging from the rubber mounts. This may cause the downpipe to make contact with the rear subframe. It is HIGHLY recommended that you replace your engine and transmission mounts to avoid fitment issues and potential rattles. Replacing the dogbone mount is a good start, but it will not always fix the issue if the motor is hanging too low.

TT225 downpipes now feature an adjustable turbo flange to help with fitment issues related to worn mounts. The adjustment may allow subframe clearance unless the mounts are too worn.

180hp TT Owners Please Note

We are aware that many 180hp FWD and 180Q owners are converting to 225 turbochargers and exhaust systems. Before purchasing any of our TT exhaust components for your conversion, please contact us to discuss your project. The internet may say "it will fit," but our experience proves otherwise. There are distinct differences between the 180FWD, 180Q and 225 stock exhaust systems that many will deny. We have proven these differences and we urge you to contact us before purchasing exhaust parts for your conversion so that we may steer you in the right direction.
